Answer question

8. In the above problems, you developed cost, revenue, and profit functions that were dependent on time. However, in business and economics, it is important to have the cost, revenue, and profit functions depend on units of product produced, which in this problem, is pounds of apples per tree. Write down cost, revenue, and profit functions that are now functions of pounds of apples per tree. (a) Find the marginal cost, revenue, and profit functions. In terms of pounds of apples, carefully explain what useful information can be gathered from marginal functions (b) Use Matlab to determine when your marginal profit function is 0. Also use Matlab to graph your marginal profit function. (c) Using the information in (b.), write down the interval(s) where your marginal profit function is positive and where it is negative. How do you interpret a positive marginal profit function? I negative marginal profit function? (d) How many pounds of apples per tree is optimal
